Alto's Adventure was originally developed by Built By Snowman. Players can pick from one of six unique snowboarders, each of which has their own unique skills and abilities, to control and guide through a number of different settings. The game includes procedurally generated terrain that's based on real-world snowboarding, along with physics-based gameplay with dynamic lighting and weather effects.

The Android version is being handled by Noodlecake Studios, who state:

We couldn't be more excited to get to work with this amazing title and the great team over at Built by Snowman. We are hoping to have the game out soon enough but we don't have an exact launch date just yet.

This right here, people still don't seem to understand this. Devs go where they can make the most money, that is currently (and for the foreseeable future) iOS. I am just happy it is coming to Android.
